• No sharing or communication during the exam (in-person, texting, chatting, etc.)
• All questions will be straight answers. This means there will be no images printed nor files submitted.
• Partial credit is not to be expected and is available only under specific and unique situations.
• The exam will be given to you in print and online. You will fill the answers on the print paper and submit it.

Sample Questions

1. Create a layer representing the slope of Arlington Quad. If you create 10 equal classes, what is range that represents the highest values (steepest)? [31.92996713 - 35.47774124]
   
1. Data
2. projectednad83 file elevation is meters and spatial reference is nad83 (arctoolbox/data management tools/projections & transformations/raster/project raster) - Use UTM NAD1927 Zone 14N -OR- Set data frame to that reference and export raster same as data frame
   
2. Create a layer representing the distance (in feet) from major roads in Tarrant County. If you create 10 equal classes, what is the range that represents the highest values (furthest)? [33,601.44376 - 37,334.9375]
   
1. If you do not have a major roads file readily available,download pizza demo for major roads (arterials)
   
3. Situation: Particular animal species known to always travel within .5 km of a particular vegetation type. If you were to create a reclassification scheme of the distance to this vegetation type, in order to identify possible locations to find the species, (1) what is the minimum number of classes you need to create? and (2) what would be the break points of these classes? [2 classes] [.5 km and max value]
   
4. If you needed to include population density, that was obtained from the American Factfinder Census website, as an input into suitability analysis, would you use distance-straight line or convert feature to raster? [convert feature to raster]
   
5. An analyst used the Raster Calculator to multiply two raster layers together. Afterward, he could not locate the generated Grid file to back up his work? What could he have done to ensure that the result of the Raster Calculator will store the result in a folder of his/her choosing? [specify working directory in spatial analyst options]
   
6. Take these two raster files and compute a weighted average. The weight of the d_roads file will be 25% and the wieght of the income file will be 75%. If you create 15 equal classes, what is the range that represents the highest values? (data) [394,166.8793 - 422,321.6563]

Exercise #1

• Convert this table into a shapefile.
• First convert to temporary event class
  
• Right-click/Display XY Data
• X: Long
• Y: Lat
• Spatial Reference: NAD 83
• Second export the event class to new shapefile
• Right-click/Data/Export Data
  

Exercise #2

• Convert this table into a shapefile exclusively using the Geoprocessing Tools. (No right-clicking and no toolbars.)
• Create Temporary Layer: ArcToolbox/Data Management Tools/Layers and Table Views/Make XY Event Layer
• Copy to New Shapefile: ArcToolbox/Data Management Tools/Features/Copy Features

Exercise #3

• Create an Automated Model that does the same thing as the above procedure.

1. Create a new Toolbox in ArcCatalog (right-click/New Model)
2. Add this Toolbox to ArcMap (right-click ArcToolbox/Add Model)
3. Create a new Model in the Toolbox (right-click/New Model)
4. Edit Model (Right-click Model/Edit)
